Mets' Francisco Alvarez hits grand slam in latest rehab game with Triple-A Syracuse

Francisco Alvarez is getting closer to a return to the Mets, and in his potentially final rehab game with Triple-A Syracuse, the backstop showed his prodigious power.

After flying out in his first at-bat against Buffalo on Wednesday, Alvarez came up to the plate with the bases loaded and two outs in the fourth inning. Stepping to the plate against CJ Van Eyk, Alvarez was down 0-2 in the count when a fastball was left up in the zone. Alvarez got around the pitch and launched the ball 405 feet — at 105.6 mph — for the grand slam. The blast gave Syracuse a 7-0 lead.

Alvarez finished 1-for-4 with a walk but caught all nine innings of Syracuse's 8-2 win on Wednesday. In five games with Triple-A, Alvarez is 4-for-19. 

In addition to Alvarez, the Mets had Jose Siri rehabbing with Triple-A. In his second game with Syracuse, Siri went 1-for-4 with two RBI and a run scored. Siri was the DH in Tuesday's game, but played center field on Wednesday for seven innings before he was pulled. In two games, Siri is 2-for-9 with two RBI and four strikeouts.

In the prospect department, Jett Williams went 2-for-4 with a walk and a run scored. His big hit came in the eighth, a two-run shot that went 384 feet. 

Carson Benge and Ryan Clifford went a combined 0-for-8 with a walk and an RBI, and four strikeouts. 

Kevin Parada made his Triple-A debut after his promotion and started as the team's DH. He went 1-for-4 with a walk and a run scored. He also stole a base.
