Miguel Sano had a 9 a.m. appointment for an MRI, and the Twins are still waiting for him to return and the results to be read.

Twins manager Paul Molitor still doesn't know how Sano was injured, but pointed out that the big man has fouled some pitches off in the area during the season and thinks it might have just flared up on him.

Joe Mauer is getting the day off, which is standard Mauer maintenance. That leads to one of the more interesting lineups of the year. Byron Buxton is batting third - how far has he come? The center fielder is batting .375 over his last 24 games and has a career high nine-game hitting streak.

Molitor said there was no special message behind batting Buxton third, that he needed to balance out the lineup. But he sure didn't put anyone else there. To me, the two biggest developments of the second half have been Buxton and Eddie Rosario. Rosario's surge has allowed Molitor to bat him behind Sano for protection and put Mauer in front of Sano (which makes more sense) and Buxton has provided a spark at the bottom of the order.

And that's what happens sometimes with development. I remember the end of the 2000 season, we were chatting with Tom Kelly that the guys he's been yelling at for two years were finally starting to play better. In 2001, they were 50-31 before a second half collapse. In 2002, they won the first of several division titles.

Hector Santiago is out playing catch right now as he tests his left shoulder area after receiving a cortisone shot earlier this week. Santiago said the soreness is something he's dealt with for awhile but, "pitched around." The guess here is Santiago will throw a bullpen session or two before going back to Rochester to pitch in games.

The challenge for Bartolo Colon, if he chooses to accept it, is to complete the circle. Colon is 0-2 with a 3.42 ERA in four starts against Arizona. THE DIAMONDBACKS ARE THE ONLY TEAM HE HAS NOT BEATEN IN HIS CAREER.

Forgot to mention this. This has been a little bit of a reunion weekend for Robbie Grossman and Paul Goldschmidt. The two grew up near each other in the Houston area and played on the same traveling team. Grossman casually mentioned that Anthony Rendon also was on the team. Then he mentioned that Matt Purke, a first-round pick of the Rangers in 2009, also was on the team. I asked him, "Did you guy ever lose?" "We were really good," Grossman said.
