ARLINGTON, Tex. — You might think that Manager Bo Porter, after watching his Houston Astros stagger to 108 losses, might enjoy some time away from the team this winter. The Astros, whose season mercifully ends at home against the Yankees this weekend, have set a franchise record for defeats.

“We can’t do this year in and year out,” Brandon Barnes, a rookie outfielder, said after the latest loss, to the Texas Rangers on Wednesday. “It’s not fun for anybody.”

Porter, though, cannot get enough. He has the entire season cataloged on the hard drive of his computer, and he said he would watch all the games again this winter.

Every last pitch.

“There’s a lot of learning material there,” Porter said. “I’m a firm believer: if you get better at the things that cause you to lose games, it increases your chances of winning.”
