"I wanted to pitch with guys on base," Arrieta said. "I wanted to work on pitching from the stretch with good timing, good rhythm, good tempo. It was nice to have a guy like Jemile [Weeks] on base, a guy who's fast, a guy who I had to vary some times and who I had to pick over."
Weeks collected the first hit off Arrieta with a leadoff single in the third.
"[The walk] was intentionally unintentional, I guess, in the second, but a good situation to work on," Arrieta said.
Colin Rea, who is competing for a spot in the Padres' rotation, walked three and gave up one run on one hit over four innings. He hadn't allowed a run all spring entering the outing, and he had only allowed four hits over five innings. But he got to work out of the stretch quite a bit on Monday, which he saw as a positive.
"I felt like I needed to get in those situations, because you're not going to be your best every time out," Rea said. "It's definitely [good] to get in those situations during Spring Training so you're used to them during the season."
The Cubs took a 1-0 lead in the first on Kris Bryant's two-out RBI double off the left-field wall, but the Padres tied the game in the third when Weeks singled, stole second, and scored one out later on a Jon Jay double that Soler misplayed.
In the San Diego fifth, Travis Jankowski lined a single to left off Pierce Johnson that dropped in front of a sliding Soler, and rolled all the way to the warning track. Jankowski didn't stop running, and scored on the error to give the Padres a 2-1 lead. But the Cubs tied the game in their half on Dexter Fowler's RBI single.
Blash connected with two outs and one on in the sixth off Johnson, who then walked Alex Dickerson to set up Ramirez's home run. Johnson allowed five runs on four hits in his two innings.
