The Pirates announced they’ve traded relief pitcher Kyle Nicolas to the Reds for left fielder/second baseman Tyler Callihan. Both players were on the 40-man roster, so there’s no corresponding move.
It’s a swap of talented but largely unproven players between the NL Central rivals. Nicolas, 27, has the more significant MLB experience of the two. A second-round pick by the Marlins in 2020, he was traded to Pittsburgh as one of two prospects the following year for Gold Glove catcher Jacob Stallings. Nicolas was a starting pitcher at the time but always projected to a bullpen future because of spotty command.


Nicolas debuted as a September call-up in 2023. The Ball State product has opened each of the following two seasons on optional assignment to Triple-A Indianapolis. Nicolas has posted below-average numbers at the MLB level but remains an intriguing depth piece with big stuff.
In 98 MLB innings, Nicolas carries a 4.68 earned run average. He has struck out a league average 22% of opponents while issuing walks at a lofty 12.2% rate. He split his time evenly between the majors and Triple-A last year. While he allowed nearly five earned runs per nine at the MLB level, he posted a 3.79 ERA with an excellent 31% strikeout rate against minor league opposition. Nicolas walked more than 12% of Triple-A opponents and has posted double digit walk rates at almost every stop of his professional career.
The command will probably keep Nicolas in middle relief. He’d have the raw stuff to pitch at the back of a bullpen if he can find a way to throw more strikes. Nicolas sits in the 97-98 mph range with his heater and has a pair of power breaking balls: a 90-91 mph slider and mid-80s curveball.
He also uses his 6’3″ frame to get down the mound and generate a lot of extension, though the long levers have also seemingly held him back from finding consistency in his delivery. Nicolas commanded the ball better down the stretch last season. He walked only 8.4% of opponents while posting a 3.46 ERA in 26 innings after the All-Star Break. It’s a small sample but perhaps something to build off as he tries to earn a permanent bullpen spot.
Nicolas has a little over one year of service time. He’s at least two years away from arbitration and five years from reaching free agency. He has one minor league option remaining, so the Reds can send him to Triple-A Louisville without exposing him to waivers. Nicolas tossed two scoreless innings this spring before joining Team Italy for the World Baseball Classic. (He’s from Ohio but has a family link to Italy that made him eligible to participate.)
Cincinnati doesn’t have a ton of roster flexibility in the bullpen, where six of their relievers cannot be optioned. Graham Ashcraft has options but is a lock to begin the season in the late innings. Unless the Reds move on from Sam Moll, they’d only have one bullpen spot available between Nicolas, Luis Mey, Connor Phillips and Zach Maxwell. The latter four pitchers all have big arms but come with strike-throwing questions.
The Pirates subtract from their bullpen depth to take a flier on an intriguing hitter who hasn’t found a position. The 25-year-old Callihan was an overslot third-round signee out of high school in 2019. Scouts have praised the lefty hitter’s offensive aptitude while panning his defense. The Jacksonville native has a career .262/.332/.417 batting line over six minor league seasons.


Callihan’s performance in the low minors was a little inconsistent. He has posted better numbers as he’s climbed the minor league ladder. Callihan hit .271/.345/.413 in Double-A two seasons ago and was out to a .303/.410/.528 start over 24 Triple-A contests last year. The Reds called him up at the end of April.
Unfortunately, Callihan didn’t get a chance to establish himself as a rookie. He suffered a gruesome injury just six days into his big league career.
Callihan was playing left field against the Braves on May 5. Matt Olson hit a line drive that sliced away from him down the left field line. Callihan slid to try to catch the ball and was unable to brace himself before hitting the wall with his outstretched glove hand. The collision broke his arm and forced him to undergo season-ending surgery. (Adding insult to injury, Olson trotted around for an inside-the-park home run because Callihan had touched the ball in fair territory.)
That ended his debut campaign after six at-bats, in which he collected his first career hit and run batted in. Callihan entered Spring Training without any restrictions and has gotten into seven exhibition contests, going 2-9 with a home run.
Baseball America ranked Callihan the #20 prospect in the Cincinnati system over the offseason, while Eric Longenhagen of FanGraphs slotted him 29th in the organization. Callihan has improved his plate discipline and has above-average raw power, but his strikeout rate has climbed in the upper minors.
He’s a below-average defender at second base who probably fits better in left field or at first base. There are some similarities to last winter’s Spencer Horwitz pickup in that regard, though Horwitz had a much longer track record of hitting in Triple-A than Callihan does.
Callihan has less than one year of service and has two minor league options remaining. He’ll battle for a bench job in camp but seems likelier to begin the season in Indy. He can factor in as a bat-first utility type throughout the season if he’s hitting well in the minors.
