FORT MYERS, Fla. -- Making his sixth Grapefruit League start, right-hander Mike Pelfrey allowed four runs on five hits and three walks over four frames in the Twins' 7-4 win over the Red Sox on Saturday afternoon at JetBlue Park.
Pelfrey went 1-0 and posted a 3.57 ERA over 17 2/3 innings this spring. He allowed seven earned runs, 16 hits, one home run, issued six walks and notched nine strikeouts.
"Overall, I've had a good spring," Pelfrey said. "Today, the ball was flat and the ball was up. I don't care if I'm facing Little Leaguers or the defending World Series champs, I'm going to get hit. And, obviously, they hit the ball very hard.''
Pelfrey, entering his second season with the Twins, went 5-13 with a 5.19 ERA last season. He is scheduled to make his next start April 4 in Cleveland, the Indians' home opener.
"Last year, our biggest struggle was starting pitching," Pelfrey said, "and I think it's going to be a night-and-day difference. If you are going to turn it around, pitching is the way to turn it around. One through five, we'll be able to keep us in games and give us a chance -- and that is all you can ask for."
In eight Major League seasons, seven with the Mets, Pelfrey is 55-67 with a 4.48 ERA.
Bartlett, Kubel part of Opening Day roster
FORT MYERS, Fla. -- After inking Minor League deals and being non-roster invitees to Major League camp, Jason Bartlett and Jason Kubel landed spots on the Twins' 25-man roster.
The club selected the contracts of both players Saturday morning and reassigned catcher Dan Rohlfing to Minor League camp.
Kubel played seven seasons with the Twins before leaving as a free agent prior to the 2012 campaign. The 31-year-old hit just .216/.293/.317 with five homers, nine doubles and 32 RBIs in 97 games with the D-backs and Indians last season. He played 89 of those games with Arizona before being traded to Cleveland on Aug. 29.
Kubel, who was originally selected by the Twins in the 12th round of the 2000 First-Year Player Draft, was a .271/.335/.459 hitter with 104 homers, 142 doubles and 429 RBIs in 753 games with Minnesota.
Bartlett, who was with the Twins from 2004-07, last played in the Majors in '12 with the Padres, and he didn't play at all last season.
Bartlett, 34, was limited by a sprained right knee in 2012, hitting just .133 in 33 games before being released by San Diego that August.
He's a career .271/.336/.366 hitter with 31 homers, 156 doubles and 123 stolen bases in 889 career games. He served as Minnesota's starting shortstop from 2005-07 before being traded to Tampa Bay before the '08 season in the deal that brought Delmon Young to the Twins.

• Twins prospect Adam Brett Walker II went 2-for-2 with a home run, double, run scored and an RBI on Saturday. Facing Red Sox left-hander Tommy Layne in the seventh inning, Walker hit a two-run home run on the on the first pitch of his first plate appearance in a big league game this spring.
