Schwarber, who lost at least 20 pounds this offseason, was eager to get Spring Training started.
"He's jacked up to play," Maddon said. "I don't know what I said to him [pregame], but his response was that it's so great to get going again. He's talking about a game on Feb. 23 at Maryvale. He worked so hard, and he wants to get back out there, seeing it with first-time eyes, feeling it with first-time passion. That's what he's doing."
• Tommy La Stella hit an RBI single in the third inning in the Cubs' 2-1 loss to the Brewers on Friday in the Cactus League opener. The Cubs totaled five hits, including a double by Mark Zagunis. Lefty Dario Alvarez took the loss, serving up two hits, including Eric Sogard's two-run triple, and two walks in one inning.
• Ben Zobrist, who has not taken part in drills this week because of back soreness, joined the players for pregame stretching on Friday.
"They're just introducing things slowly," Maddon said. "I've already told him to not hurry, so he's not hurrying. He's doing well."
• It was an unseasonably cool 59 degrees for the start of Friday's game. The cool temperatures in Arizona are not conducive to Maddon's workouts.
"It's really impacting my bike rides," he said. "I don't like to ride when it's this cool. ... It has something to do with global cooling."
Up next:Eddie Butler will start the Cubs' home opener at Sloan Park on Saturday, facing the Rangers and right-hander Clayton Blackburn. First pitch is scheduled for 2:05 p.m. CT. Anthony Rizzo is expected to start. The Cubs will wear the Marjory Stoneman Douglas High School caps for the game.
