| Mar 2 2024 | Martinez was optioned to Triple-A Las Vegas by the Athletics on Saturday. | ROTOWIRE RECOMMENDS: Martinez received a quick cut from camp after yielding four runs over 1.1 innings in his two Cactus League outings. The 27-year-old could be used as a starter or reliever at Las Vegas. |
|
| Aug 29 2023 | Martinez didn't factor into the decision in the Athletics' loss to the Mariners on Monday, allowing an earned run on five hits and a walk over four innings. He also recorded a strikeout and uncorked two wild pitches. | ROTOWIRE RECOMMENDS: Control issues aside, Martinez provided some valuable length for manager Mark Kotsay after starter Kyle Muller was chased following four innings. Martinez has allowed at least one earned run in each of the five appearances he's logged since being promoted from Triple-A Las Vegas on Aug. 8, but the combination of his versatility and the slew of pitching injuries the Athletics are still dealing with is likely to continue affording the right-hander consistent opportunities. |
|
| Aug 24 2023 | Martinez (0-2) took the loss against the Royals on Wednesday, allowing an earned run on three hits, a hit batsman and a walk over 2.1 innings. He struck out three. | ROTOWIRE RECOMMENDS: Martinez's one big mistake was deposited by Dairon Blanco into the left-field seats in the third inning for the first run of the game. The right-hander has allowed at least one run in all four appearances he's logged since returning to the majors Aug. 8 while pitching to a 5.73 ERA, 1.55 WHIP, 4.1 BB/9 and 1.6 HR/9 across 11 innings. With both Luis Medina (finger) and Freddy Tarnok (calf) on the injured list for the time being, Medina could be called on for another spot start early next week. |

| Aug 23 2023 | Martinez is listed as the Athletics' starting pitcher for Wednesday's game against the Royals, Martin Gallegos of MLB.com reports. | ROTOWIRE RECOMMENDS: Martinez has made 12 starts at Triple-A Las Vegas this season, but he's been working exclusively as a reliever across multiple stints with Oakland, compiling a 5.85 ERA and 1.42 WHIP in 32.1 innings over 14 appearances. Since he's reached four innings just once this season for the Athletics and will be pitching on three days' rest after making a one-inning appearance Saturday against the Orioles, Martinez is unlikely to reach the five innings he would need Wednesday to qualify for a win. Instead, look for the Athletics to treat Martinez as a multi-inning opener in front of Kyle Muller, who is available to pitch on four days' rest. |

| Aug 9 2023 | Martinez, recalled from Triple-A Las Vegas earlier in the day, allowed two earned runs on four hits and three walks over 4.2 innings during a loss to the Rangers on Tuesday. He recorded five strikeouts and did not factor into the decision. | ROTOWIRE RECOMMENDS: The young right-hander was afforded an 82-pitch assignment right out of the gate in his first taste of major-league action since May 26. Martinez ate up some valuable innings in the process, getting all but the last out of the night for the Athletics after starter J.P. Sears exited following four laborious frames. Martinez is slotting into a bullpen role for the time being, but as the length of Tuesday's appearance indicates, he's capable of serving in a bulk-relief capacity or even moving into the rotation if necessary. |
|
| Aug 8 2023 | Oakland recalled Martinez from Triple-A Las Vegas on Tuesday. | ROTOWIRE RECOMMENDS: Martinez has struggled to a 5.70 ERA across 23.2 innings this season at the major-league level, but the Athletics need fresh bullpen arms as they play out the string in 2023. Dany Jimenez was optioned out in a corresponding roster move. |
|
| May 27 2023 | Martinez was optioned to Triple-A Las Vegas on Saturday, Matt Kawahara of the San Francisco Chronicle reports. | ROTOWIRE RECOMMENDS: Martinez will head to Las Vegas after posting a 2.84 ERA and 1.42 WHIP with six strikeouts over 6.1 innings in five appearances during his second stint with Oakland this season. The 26-year-old will likely get another shot with the Athletics this summer, but for now, Hogan Harris was recalled from Triple-A and will serve as the bulk relief pitcher following opener Austin Pruitt versus the Astros on Saturday. |
|
| May 16 2023 | Martinez, activated from the injured list earlier in the day, fired two scoreless innings in which he allowed a hit and recorded two strikeouts during a loss to the Diamondbacks on Monday. | ROTOWIRE RECOMMENDS: The right-hander needed just 22 pitches to record his six outs, a highly efficient outing that stood in stark contrast to both his prior body of work at the big-league level this season and during his recent rehab assignment. Martinez had allowed nine earned runs over his last two appearances before going on the injured list with an elbow injury, and he'd subsequently given up four runs on seven hits over 2.1 innings in his pair of minor-league turns. |
|
| May 15 2023 | The Athletics reinstated Martinez (elbow) off the 15-day injured list Monday. | ROTOWIRE RECOMMENDS: Martinez ended up missing three weeks with a right elbow strain. The right-hander has struggled to a 6.75 ERA over 17.1 innings while working out of the bullpen, and he'll likely be a middle-innings option for Oakland while he's with the roster. Zach Neal was sent back to Triple-A in a corresponding transaction. |
|
| May 14 2023 | Martinez (elbow) was charged with the loss in Triple-A Las Vegas' defeat at the hands of Albuquerque on Friday, allowing three earned runs on four hits across 1.2 innings. He struck out two and hit a batter. | ROTOWIRE RECOMMENDS: Martinez pitched to plenty of contact for the second time in as many rehab appearances, although Friday's performance was by far the poorer of the two. Given the right-hander's struggles thus far in the minors, it's possible he's afforded a few more rehab appearances to straighten matters out before activation is considered. |
|
| May 11 2023 | Martinez (elbow) made a rehab appearance for Triple-A Las Vegas on Tuesday, covering 1.2 innings while allowing one earned run on three hits and two walks. | ROTOWIRE RECOMMENDS: The Athletics are likely planning to have Martinez work as a multi-inning reliever upon his return from the 15-day injured list, and the fact that he built up to 37 pitches Tuesday could mean that he won't require any further rehab appearances prior to being activated. Before landing on the IL with a right elbow strain, Martinez logged a 6.75 ERA and 1.38 WHIP in 17.1 innings out of the Oakland bullpen. |
|
| May 5 2023 | Martinez (elbow) will throw an extended bullpen session Friday, the Associated Press reports. | ROTOWIRE RECOMMENDS: The right-hander was knocked around for nine earned runs across 6.1 innings over his last two relief appearances before going on the injured list April 24 with right forearm inflammation and a strained right elbow. Martinez was able to throw a bullpen session Tuesday that he apparently didn't suffer any residual effects from, setting up what is likely to be a longer session Friday. If all continues without setbacks, it's possible Martinez embarks on at least a brief rehab assignment sometime next week. |
|
| May 2 2023 | Martinez (elbow) is throwing a bullpen session on the mound before Tuesday's game against the Mariners, Matt Kawahara of the San Francisco Chronicle reports. | ROTOWIRE RECOMMENDS: Martinez has been on the injured list since April 24 with a right elbow strain. The right-hander may need a rehab stint before returning to the Oakland bullpen, but one way or another he should be throwing low-leverage innings for the Athletics by the middle of May as long there's no setback. |
