Left fielder Carlos Gonzalez will take batting practice on the field Thursday and is pushing toward an injury rehab assignment after recovering from surgery to remove a tumor from his left index finger.
Rockies trainer Keith Dugger guessed on June 11 that CarGo would be out five weeks, so he’s right on schedule. The 28-year-old was batting just .255 with a .756 OPS before the surgery, but that relative lack of production can be blamed on the tumor in his finger, which had been bothering him for much of 2014.
Gonzalez hit .302/.367/.591 with 26 home runs, 70 RBI, and 21 stolen bases in 110 games last year.
When he returns, the Rockies’ starting outfield will likely be Gonzalez in left, Charlie Blackmon in center, and Corey Dickerson in right. Michael Cuddyer is out until August with a major shoulder injury.
The Mariners have activated third baseman Kyle Seager from the 60-day injured list, per a team announcement on Saturday. Dylan Moore has been optioned to Triple-A Tacoma to clear a spot on the 40-man roster for Seager, while right-handed reliever Sam Tuivailala has been placed on the 60-day IL (ruptured Achilles tendon).
Seager, 31, suffered a partial tear in the extensor tendon of his left hand during spring training and has yet to make his season debut. He underwent surgery on the tendon in mid-March and has had a long and slow recovery since then, eventually working his way up to a few starts in Triple-A last week. Through his first nine games in the minors, he batted .256/.310/.308 with two extra bases, seven RBI, and a .617 OPS over 42 plate appearances.
Any progress is good progress, though, and the Mariners will no doubt be looking to Seager to uphold the .250+ average, 3.0+ fWAR totals of seasons past as he works his way back to a full workload — especially with fellow third baseman Ryon Healy headed to the 10-day IL with a bout of back inflammation. Seager will start at third and bat sixth when the club faces off against the Athletics at 4:07 PM EDT on Saturday.
