| Jun 10 2025 | Rainey signed a minor league contract with the Pirates on Tuesday and will report to Triple-A Indianapolis, Alex Stumpf of MLB.com reports. | ROTOWIRE RECOMMENDS: The Pirates designated Rainey for assignment June 2 after a poor outing in which he was only able to record an out with four earned runs allowed. For the season, he's had eight scoreless appearances, but three in which he gave up two or more earned runs. The 32-year-old rejoins Triple-A Indianapolis, where he has a 6.00 ERA across nine innings in 2025. |

| Jun 2 2025 | The Pirates designated Rainey for assignment Monday. | ROTOWIRE RECOMMENDS: Rainey will lose his spot on the roster after he was knocked around for four runs while recording just one out in his final appearance with the Pirates on Sunday in San Diego. He seems likely to clear waivers. |
|
| May 3 2025 | The Pirates selected Rainey's contract from Triple-A Indianapolis on Saturday. | ROTOWIRE RECOMMENDS: Rainey had a strong spring training, posting a 1.13 ERA and 0.50 WHIP with 12 strikeouts over eight innings in eight appearances, but didn't break camp with Pittsburgh. The righty reliever has posted a 6.00 ERA, 1.22 WHIP and 12:4 K:BB over nine innings with Indianapolis and will now get a shot with the big-league bullpen. Rainey will fill the 26-man roster spot that opened up when Isaiah Kiner-Falefa (hamstring) was placed on the 10-day IL on Saturday, and to make room for Rainey on the 40-man roster, Justin Lawrence (elbow) was moved from the 15-day to the 60-day IL. |

| Mar 24 2025 | Rainey was reassigned to Triple-A Indianapolis on Monday. | ROTOWIRE RECOMMENDS: Rainey will open the season at Triple-A after producing an impressive 1.13 ERA and 0.50 WHIP with 12 strikeouts over eight innings in eight appearances with the Pirates during spring training. The right-hander appeared in 50 games with the Nationals in 2024, compiling a 4.76 ERA with 44 strikeouts over 51 innings, and he'll now look to get into a groove with Indianapolis in an attempt to earn a promotion this summer. |

| Feb 26 2025 | Rainey has thrown two scoreless innings while striking out four and walking none across two Grapefruit League appearances. | ROTOWIRE RECOMMENDS: Rainey is in Pirates camp as a non-roster invitee after a down 2024 season. Last year was his first back from Tommy John surgery, and he had been effective for several years prior while working out of the Nationals' bullpen. Pittsburgh boasts a relatively deep pool of relievers, but Rainey could sneak onto the roster if he continues to perform well. |
|
| Dec 12 2024 | The Pirates signed Rainey to a minor-league contract Dec. 6 that includes an invitation to spring training. | ROTOWIRE RECOMMENDS: Rainey was non-tendered by the Nationals in November after posting a 4.76 ERA and 44:29 K:BB over 51 frames in 2024 in his first year back from Tommy John surgery. The reliever's stuff hasn't looked the same post-op, but he's a fine gamble on a non-roster deal in hopes that he can rediscover it. |

| Jul 4 2018 | The Redsrecalled Rainey from Triple-A Louisville on Wednesday. | Cincinnati will bring up a pair of relievers in Rainey and Cody Reed from Triple-A to bolster the bullpen after long reliever Dylan Floro was traded to the Dodgers prior to Wednesday's game against the White Sox. Rainey has previously made six appearances for the Reds, surrendering nine runs on six hits and nine walks over six innings. Those poor numbers will likely force him to settle for a low-leverage relief role while he's up with the big club. |
|
| May 23 2018 | Rainey was recalled from Triple-A Louisville on Wednesday. | He has given up seven earned runs in two big-league innings this year, but has been much more successful in 17.2 frames at Triple-A (2.04 ERA, 31 strikeouts). Raisel Iglesias (non-throwing biceps) and Austin Brice (back) were placed on the disabled list as corresponding moves. Look for Rainey to be used in low-leverage situations. |
|
| May 4 2018 | Rainey was called up Friday to replace Amir Garrett (bereavement). | Rainey was up briefly in mid-April, allowing seven runs on three hits and five walks in just two innings. He'll likely be up just a few days while Garrett remains on the bereavement list and is unlikely to have much fantasy value. |
|
| Apr 10 2018 | Rainey's contract was selected from Triple-A Louisville on Tuesday. | Rainey has just two innings under his belt at the Triple-A level, but he hasn't allowed a run and holds a 5:1 K:BB. He also drew raves reviews from manager Bryan Price during spring training, so it's not surprising to see him in the big leagues already. He should slot into a lower-leverage situations to start, but it's not crazy to think he could find his way into high-leverage situations if he finds success in the majors. Yovani Gallardo was designated for assignment to make room for him on the active roster. |

| Mar 7 2018 | Reds manager Bryan Price praised Rainey unsolicited before Wednesday's spring training game against the White Sox, MLB.com's Mark Sheldon reports. "He's a guy worth really watching closely," Price said. "That's a big arm, big slider. I think he's going to be a good one. I volunteered that because I haven't really spoken about him. I think he's been very impressive in camp the way he's handled himself." | Rainey has touched 98 mph on the radar a couple of times in spring training. He has a big strikeout upside in relief, but he also has walked opposing batters at a prolific clip, including 11 batters in 17 innings in a late call-up to Double-A Pensacola last year. |
