Blue Jays Acquire Tyler Fitzgerald, Option Infielder to Triple-A Buffalo

Tyler Fitzgerald, 28, is heading to Triple-A Buffalo after the Toronto Blue Jays acquired the infielder from the San Francisco Giants for cash considerations Saturday, with MLB Network's Jon Morosi reporting the deal mid-game during Toronto's matchup against the Chicago White Sox in Chicago.

The timing was no accident. Earlier that same day, All-Star catcher Alejandro Kirk was placed on the 10-day injured list with a left thumb fracture, an injury suffered when an Austin Hays foul tip struck his hand the previous night. The Kirk news triggered a cascade: catching prospect Brandon Valenzuela was recalled from Triple-A in a corresponding move, and the already-thin state of Buffalo's infield came into sharp focus. Just a week prior, on March 29, Toronto had traded infielder Leo Jiménez to the Miami Marlins for minor-league infielder Dub Gleed and $250,000 in international bonus pool money. Jiménez had been out of options. His departure left the Bisons with Rafael Lantigua and No. 13 Blue Jays prospect Josh Kasevich as the primary utility options, neither of whom is on the 40-man roster.

Fitzgerald fills that structural gap directly. With one option year remaining and already on a 40-man, he gives Toronto a piece they can shuttle to the majors without waivers exposure. An open 40-man spot meant no corresponding move was required to complete the acquisition.

San Francisco's timeline on Fitzgerald closed quickly. The Giants designated him for assignment March 30 to make room for reliever Dylan Smith, acquired from the Detroit Tigers. Luis Arraez's offseason arrival at second base had already reduced Fitzgerald to a bench role at best, and a hitless start at Triple-A Sacramento, 0-for-14 with five strikeouts across three games, gave the organization little reason to hold on. By moving him for cash rather than placing him on waivers, the Giants effectively acknowledged another club would act fast. Toronto did.

None of that erases what Fitzgerald did in 2024. He slashed .280/.334/.497 with 15 home runs, 17 stolen bases, and a 132 wRC+ over 96 games, leading all qualified MLB rookies in both categories while posting 3.0 fWAR. That July, he homered in five consecutive games and seven times in eight games, becoming the first Giant to accomplish either feat since Barry Bonds in 2004. The number underneath all of it, however, was a .380 BABIP, well above league average, which flagged the performance as partially unsustainable.

The correction arrived in 2025. His BABIP normalized to .299 and his production collapsed to .217/.278/.327 with four home runs, nine stolen bases, and a 72 wRC+ over 72 games. The Athletic's Mitch Bannon acknowledged the regression directly while still framing the acquisition as viable: Fitzgerald "wasn't great last year, but put up an .831 OPS in 2024 while crushing lefties."

His Triple-A track record offers a reliable floor. In 709 career at-bats at the AAA level, Fitzgerald has hit for an .825 OPS with 34 home runs, 117 RBIs, and 32 stolen bases in 37 attempts. His 29.6 mph average sprint speed ranked in the 97th percentile of all major leaguers in 2024 per Baseball Savant, and he has stolen 28 bases in 36 career big-league attempts across positions that include second base, shortstop, and corner outfield.

A fourth-round pick out of Louisville in 2019, Fitzgerald made his MLB debut September 21, 2023, and batted .252 with 21 home runs and 53 RBIs across 178 games in three seasons with San Francisco. Kasevich remains Toronto's preferred long-term infield call-up option if a permanent roster need opens, but Fitzgerald, with his option year and versatility, is now the organization's first phone call for anything short-term.
