2:25pm: The Pirates announced that they have claimed Simón and optioned him to Triple-A Indianapolis, with Rainey designated for assignment as the corresponding move.
1:25pm: The Pirates have claimed infielder Ronny Simón off waivers from the Marlins. The latter club designated him for assignment last week. Right-hander Tanner Rainey has been designated for assignment to open a 40-man roster spot for Simón. Mike Rodriguez first reported that Simón would be joining the Pirates. Craig Mish of the Miami Herald reported that it would be a waiver claim. Alex Stumpf of MLB.com reported that Rainey was the corresponding move.
Simón, 25, got his first major league call just over a month ago. The Marlins selected his contract on April 20th and he stuck on the roster until he was designated for assignment on May 30th. He got into 19 games and stepped to the plate 56 times, producing a batting line of .234/.327/.277.
That was a fairly unremarkable performance from a statistical point of view but Simón got thrust into the spotlight in an unusual way. As relayed Jason Foster and Christina De Nicola of MLB.com, Simón had a nightmare game against the Padres last week. The Fish were up 6-0 on Tuesday but several errors and general defensive miscues from Simón allowed the Friars to engineer an 8-6 comeback victory.
Amid the chaotic contest, Simón was seen wiping tears from his face. After the game, he received plenty of encouraging messages from his teammates and even his opponents. Per the MLB.com story, Padres such as Manny Machado, Luis Arráez and Fernando Tatis Jr. sent supportive texts to Simón after the game. In addition to that challenging on-field experience, Simón also had to deal with getting sent into DFA limbo a few days later. However, he has quickly found a new home by landing with the Pirates.
Simón’s major league time isn’t much to go on. Presumably, the Pirates are paying more attention to his minor league work. In 2,328 minor league plate appearances, he has a .266/.341/.446 line and 108 wRC+. Before getting called up this year, he got into 15 Triple-A contests and had a massive .354/.441/.521 line in that small sample.
As of July of last year, FanGraphs considered Simón to be one of the top 20 prospects in the Rays’ system, noting that his switch-hitting and defensive versatility gave him a good shot to eventually become a utility player. He has experience at the three infield positions to the left of first base as well as the outfield corners. He’s generally been able to steal about 20-35 bases annually. The Rays didn’t give him a 40-man spot at the end of last year, which led him to sign a minors deal with the Marlins coming into 2025.
He still has a full slate of options, so the Pirates can keep him in the minors if they don’t have room at the big league level. Rainey’s DFA does open an active roster spot but the Pirates might recall a pitcher rather than playing with the pitching staff shorthanded.
Rainey, 32, signed a minor league deal with the Pirates in the offseason and was selected to the roster about a month ago. He has since tossed 7 2/3 innings over 11 appearances, allowing nine earned runs. There’s surely a bit of luck in there, especially from a 35.7% strand rate that is ridiculously low, but he also hasn’t done himself any favors by walking 16.2% of batters faced. On the positive side, his 24.3% strikeout rate and 45% ground ball rate are solid numbers.
He’ll now head into DFA limbo, which can last for as long as a week. The waiver process takes 48 hours, so the Pirates could take five days to try to line up a trade. Rainey’s overall track record includes 197 big league innings with a 5.44 ERA. From 2019 to 2024, he logged 182 1/3 of those innings with a 4.49 ERA, 28.5% strikeout rate and 14.1% walk rate.
