Out since May 11 with a sprained left knee, Desmond Jennings began a minor-league rehab assignment yesterday at Single-A by going 1-for-3 with a double.
He also tested his knee by playing left field and is expected to move his rehab stint to Triple-A, with Joe Smith of the Tampa Bay Times reporting that Jennings could come off the disabled list as soon as Tuesday.
In his absence the Rays have used four different players in left field, with Matt Joyce getting the bulk of the starts and Ben Zobrist playing right field rather than second base.
The Pirates announced on Wednesday that the club acquired infielder Erik González along with minor league pitchers Tahnaj Thomas and Dante Mendoza in exchange for outfielder Jordan Luplow and infielder Max Moroff.
González, 27, is quite versatile, having played all four infield positions as well as both outfield corners. He has just a .681 career OPS across 275 plate appearances in the big leagues, though. González will provide infield depth for the Pirates, who are losing Josh Harrison and Jordy Mercer.
Thomas, 19, completed his second season at rookie ball. He pitched 19 2/3 innings, yielding 10 earned runs on 13 hits and 10 walks with 27 strikeouts.
Mendoza, 19, also just completed his second season at rookie ball. The right-hander pitched 37 1/3 innings, allowing 19 earned runs on 33 hits and 20 walks with 37 strikeouts.
Luplow, 25, has played 64 games in the big leagues as an outfielder, mustering a paltry .644 OPS in 190 plate appearances.
Moroff, 25, has played second base, third base, and short stop in the majors. He carries a career .625 OPS in 209 trips to the plate.
