Buster Posey is not in the Giants lineup for the first game of Saturday's doubleheader against the Rockies.
He'll be back in there behind the plate for the nightcap. Andrew Susac is starting in his place behind the dish and will bat eighth against Jordan Lyles.
Anthony Rendon (knee, oblique) took full batting practice for the first time on Saturday and has been cleared to begin playing in simulated games next week.
He'll play in a few simulated games in Viera early in the week before heading out on a minor league rehab assignment. At this stage, barring any setbacks, he should be cleared to rejoin the Nationals in early June.
Tanner Roark will start for the Nationals on Monday against the Cubs.
That will push Jordan Zimmermann back a day until Tuesday and line Roark up for a pair of starts next week. He'll occupy the spot in the Nationals rotation until the ailing Doug Fister returns and is certainly worth a look in all mixed leagues.
Joe Mauer is not in the Twins starting lineup for Saturday afternoon's contest against the White Sox.
It's only the second day off on the season for Mauer, and comes in a nice spot against tough southpaw Chris Sale. Look for the Twins' team leader in RBI to be back in there at first base on Sunday.
Chris Johnson (hand) is expected to begin a three-game minor league rehab assignment with Triple-A Gwinnett on Monday.
He's playing in another game at extended spring training on Saturday and is expected to take batting practice with the team in Atlanta on Sunday before heading out on the rehab stint. He's slated to return from the disabled list on Thursday.
Rockies activated RHP Brooks Brown from the 15-day disabled list.
He'll take the place of Ken Roberts in Rockies bullpen who was placed on the disabled list on Saturday. The 29-year-old owns a 4.50 ERA, 1.29 WHIP and 8/5 K/BB ratio in 14 innings on the year.
Rockies placed LHP Ken Roberts on the 15-day disabled list with left elbow inflammation.
The 27-year-old appeared in eight games for the Rockies, compiling a 5.00 ERA, 1.56 WHIP and 5/2 K/BB ratio over nine innings. To take his place in the bullpen, Brooks Brown has been activated from the disabled list.
Devin Mesoraco (hip) suffered a setback in his recovery when he experienced continued pain while attempting to squat on Friday.
With this setback, he's unable to serve as the team's designated hitter over the weekend in Cleveland, but could still be available as a pinch hitter. It still looks as though the Reds will let him fight through the injury and avoid a trip to the disabled list.
