The White Sox are having the most disappointing season in baseball. The White Sox could still win the American League Central.
The White Sox could be 1 1/2 games out of first place by Wednesday. Or the White Sox could be sellers by Wednesday.
It's a time of year where things change quickly, with teams assessing their needs and chances daily.
Even by that standard, the White Sox are a team to watch this week.
They begin the week two games under .500, and 4 1/2 games behind the first-place Tigers. The Tigers are in Chicago for three games starting Monday night.
By the time the series ends Wednesday, the White Sox could be a true contender. Or they could be so far out of it that they go into full sell mode, looking to deal a pitcher like Edwin Jackson and perhaps outfielder Carlos Quentin.
Or maybe they're still left guessing whether they're in it or not. Maybe all they can do is to contemplate possible deals like the one the St. Louis Post-Dispatch reported on Sunday, where they would trade a major leaguer for another major leaguer (in this case, a pitcher like Jackson for Cardinals center fielder Colby Rasmus).
There are other teams to watch this week, notably the Rays, who have fallen 6 1/2 games out in the wild-card race after losing two of three in Kansas City.
But no team has been as disappointing this year as the White Sox, and no team will be as interesting to follow over the next few days.
On to 3 to Watch:
1. Partly because of the trade deadline, and partly because Roy Halladay and Cliff Lee won't start in the series, the Giants' visit to Philadelphia doesn't feel as big as it probably should. It's still worth watching, and it's worth noting that the Phillies allowed fewer runs over the first 100 games of the season (332) than any team since the 1989 Dodgers. Vance Worley is one of the surprising reasons for that, and Worley faces Tim Lincecum in Giants at Phillies, Tuesday night (7:05 ET) at Citizens Bank Park.
2. The White Sox began the second half by beating Justin Verlander and Max Scherzer on back-to-back days in Detroit, then missed a chance to sweep the series when they lost to Brad Penny. They get Verlander and Scherzer again in this series, with Verlander facing Mark Buehrle in Tigers at White Sox, Tuesday night (8:10 ET) at U.S. Cellular Field. Also worth watching: Jake Peavy's velocity when he faces the Tigers on Wednesday. In Peavy's last start, in Kansas City, his average fastball was below 90 mph.
3. The Mariners are also a team to watch this week, and not just because they've lost a club-record 15 straight. On a market short of starting pitcher, the M's have made Jason Vargas and Doug Fister available, and those two start Monday and Tuesday against the Yankees. They have not made Felix Hernandez available, and they're hoping that Felix won't be trying to break a 17-game losing streak when he faces Phil Hughes in Mariners at Yankees, Wednesday afternoon (1:05 ET) at Yankee Stadium. The Yankees will be hoping that Hughes looks a lot better than he did in his last start, last Friday against the A's. The M's have won each of Hernandez's last five starts against the Yankees.
