Some numbers to chew on heading into tonight’s Red Sox-Cubs series finale at Fenway (7 p.m., on ESPN).
• The Red Sox are one of four defending World Series champions to have three or more rookies start at least 40 games in a season (Xander Bogaerts, Jackie Bradley Jr., Brock Holt), and the first to do so since the 1998 Marlins had 5 such players.
• The Red Sox have had eight different players play in right field; only the Mariners have had more. They’ve also had seven players play first base, which is tied for the most this season (with five other teams).
• Boston beat up on teams under .500 last season. The Sox have not been able to take advantage of those games in the same way this season.
• They have scored 10 total runs in their past seven games at Fenway Park, spanning 66 innings.
• The Red Sox rank last in the American League and 26th in baseball in runs scored. The last time they finished in the bottom seven in runs scored was 1993.
• Many of the Red Sox’s key hitters struggled mightily in June. Among their 10 players with at least 50 plate appearances in the month of June, six of them batted below .250.
• Brock Holt has played five different positions for the Red Sox this season (all three outfield spots, first base and third base). He’s one of 15 players to play five or more positions this season in the majors and he’s one of just four to start at five or more different positions along with Leury Garica, Willie Bloomquist and Eduardo Escobar.
• About tonight's Red Sox starter: Brandon Workman has been a bright spot for the Red Sox this season; his 1.07 WHIP leads the team among the 7 pitchers who have thrown at least 40 innings this season.
He’s pitched well, but probably not as well as his 3.27 ERA would indicate. So far this season, batters have only hit .230 against him when putting the ball in play (.351 last season). For instance, only 50 percent of line drives hit off Workman have gone for hits this season after 83 percent did last year (league average is 66 percent).
Workman doesn’t have a dominant fastball -- most of his success has come with the rest of his repertoire (cutter, curveball, changeup).
