CHICAGO -- Javier Baez, who came out of Monday's game with tightness in his right groin, tried to talk his way into Tuesday's lineup but Cubs manager Joe Maddon decided not to start the infielder.
"He feels fine," Maddon said before the Cubs' 4-3 victory on Tuesday night. "He came in and reassured me that he feels good. Talking to the trainers ... I thought it was wise [to wait]."
Baez, who has 10 home runs and led the Majors with 32 RBIs, did enter as a pinch-hitter and stayed to play third, making a great defensive play on Miguel Rojas' hard-hit ball for the second out in the ninth.

On Monday night, Baez made an awkward play to throw out Justin Bour to open the seventh, and Brian Anderson then doubled. Baez was not involved on Anderson's ball, but Maddon and athletic trainer Nick Frangella went out to check on him, and then removed him from the game.
"It was kind of sore and it was cramping for a second or two," Baez said. "Everything's good."

Roster moves
• Right-handed reliever Cory Mazzoni was recalled from Triple-A Iowa on Monday and pitched one inning, but he was headed back to the Minor League team on Tuesday, as the Cubs added lefty Rob Zastryzny to the bullpen. Zastryzny had a 2.35 ERA in eight games at Triple-A Iowa, striking out 13 and walking nine over 15 1/3 innings.
In 2016, Zastryzny posted a 1.13 ERA in eight games with the Cubs.
Mazzoni had been added to provide a fresh arm to the bullpen after back-to-back extra-inning games over the weekend against the Cardinals.
• Jen-Ho Tseng was called up from Iowa to start Tuesday night in place of Yu Darvish, who was placed on the 10-day disabled list with flu-like symptoms. That move allowed Maddon to give catcher Willson Contreras a breather and start Victor Caratini on Tuesday. Maddon wants Contreras to be matched up with Darvish and Jonathan Lester.
