MINNEAPOLIS -- The Twins officially activated left-hander Scott Diamond from the 15-day disabled list before his start against the Mets on Saturday, and they optioned right-hander Liam Hendriks to Triple-A Rochester to make room for him on the roster.
The Twins decided to option Hendriks instead of left-hander Pedro Hernandez, who gave up one run on four hits over 4 1/3 innings in long relief Friday. Hernandez, who left the game with a left calf strain, is expected to join the rotation.
"Hernandez came in today, and he's fine," Twins manager Ron Gardenhire said. "He should be ready to pitch in four or five days. They're thinking it's a cramp or a slight strain but nothing bad. All the belief is that he's fine, and he's throwing the ball fine, so that made our decision."
Gardenhire said he was still working to sort out the rotation for the club's coming series against the Angels, as Hendriks was slated to start Tuesday. Gardenhire said it was possible right-hander Vance Worley could start Tuesday on short rest, with Hernandez getting the start Wednesday.
"We're kind of ad-libbing here on how we're going to run all these things there," Gardenhire said. "Worley threw just 57 pitches last night, so there's a chance he could even come back Tuesday."
Hendriks made two starts this season, posting a 4.66 ERA with five strikeouts and one walk in 9 2/3 innings. He fared well in his last outing, giving up a run against the Royals, but he lasted just five innings.
"He has to make better use of his pitches and go deep into games," Gardenhire said. "The last outing was better, where he moved the ball in and used his breaking ball to keep hitters off-balance. He just has to start doing that from inning one. So he'll have to go down to Triple-A and work on that."
Gardenhire: Florimon's sitting not due to miscues
MINNEAPOLIS -- Shortstop Pedro Florimon was on the bench Saturday in favor of Eduardo Escobar a day after making his third error in eight games this season.
Twins manager Ron Gardenhire, though, said it was just a planned off-day for Florimon, as it gave Escobar just his third start of the year.
"My plan was for Eskie to play today no matter what," Gardenhire said. "I wanted to get him back out there and get some swings."
But Gardenhire did say he had been surprised by Florimon's struggles defensively, as Florimon had an impressive Spring Training and was known for his defense during his time in the Minor Leagues.
"I wish I could figure out a way to help him," Gardenhire said. "We know how well he caught the ball [in Spring Training]. But I'm sure the cold weather has affected him. But he has to work his way through it."
Twins to place outfielder Ramirez on paternity list
MINNEAPOLIS -- The Twins will place outfielder Wilkin Ramirez on the paternity list Sunday, the club announced after Saturday's 4-2 loss to the Mets.
Ramirez, who is hitting .200 in five games this season, is heading to New York to attend the birth of his second child.
The club will wait to announce the corresponding roster move to replace Ramirez, as Sunday's game could be postponed because of weather.
Ramirez can be away from the club for a maximum of three days under the rules of Major League Baseball's paternity list.
• Right-hander Cole De Vries began his throwing program Saturday, as he played catch for the first time since being placed on the 15-day disabled list with a right forearm strain Sunday. There is still no official timetable for his return, but he was shut down for just eight days after receiving the diagnosis.
• Right-handed reliever Tim Wood, who is on the 15-day disabled list with a right rotator cuff strain, made his second appearance in an extended spring training game Saturday. He pitched two innings and will pitch in back-to-back games early next week before officially going on a rehab assignment.
