Top Mariners prospect Taijuan Walker will make his 2014 big-league debut on Monday, Greg Johns of MLB.com reports. (The Mariners optioned outfielder Stefen Romero to Triple-A Tacoma after today’s game, so it appears they’ll have space for Walker on their active roster.) Walker figured to be a key part of Seattle’s rotation this season, but he had shoulder troubles in spring training. Walker has made eight starts this season across three minor league levels, posting a 3.38 ERA with 10.4 K/9 and 2.7 BB/9. Elsewhere in MLB’s West divisions:
- Diamondbacks right-hander Brandon McCarthy will receive a $1MM assignment bonus if he is traded, tweets ESPN’s Buster Olney. The Diamondbacks will likely have to eat that sum in any deal, Olney adds.
- Eric Chavez says retirement is a “possibility” after being transferred to the 60-day disabled list by the Diamondbacks, writes MLB.com’s Steve Gilbert. “I’m just so close to the end, you know, where I’ve got to worry about feeling good for the rest of my life,” said Chavez, who is dealing with an injured left knee. “So surgery would be the worst-case scenario for me to kind of be going down that line.”
- The slumping Rockies have been hit hard by injuries with nine players currently on the disabled list, but are not yet ready to become sellers at the Trade Deadline, according to Nick Groke of the Denver Post. “We’ll get to see our club whole, or closer to the point we know it should be,” Assistant GM Bill Geivett said. “At that point we’ll sit down and discuss where we’re at.“
