Lester pitched a four-hitter for Chicago's first complete game of the season, and the Cubs beat Cueto and the San Francisco Giants 4-1 on Tuesday in a rematch of last year's playoff opener. Anthony Rizzo hit a two-run homer as Chicago improved to 5-2 on its nine-game home stand. Kyle Schwarber and Jason Heyward also connected, helping the Cubs bounce back from their 6-4 loss to the Giants on Monday night. Lester and Cueto hooked up in a memorable pitchers' duel in Game 1 of the NL Division Series last October, with Chicago winning 1-0 on Javier Baez's eighth-inning homer. Cueto (4-4) was just OK, striking out eight in six innings, but surrendering Chicago's three homers. After the first four batters struck out, Schwarber drove a 3-2 pitch from Cueto over the bleachers in right and onto Sheffield Avenue for his seventh homer. The Cubs recalled RHP Felix Pena from Triple-A Iowa and optioned LHP Zac Rosscup to their top farm club. Giants: CF Denard Span (sprained left thumb) was held out of the starting lineup for the second straight day.
