My selection is on the 'over' between San Francisco and Chicago at 8:05 pm et on Tuesday.

I absolutely love the way this one sets up as a high-scoring affair and fully expect to see the total bump up a run or so before the end of the day (I still like the over if that move happens). Tyler Beede will take the ball for the Giants. His ERA has risen to its highest point since late June as he has been tagged for a whopping 22 earned runs on 40 hits over just 23 1/3 innings in his last five starts. Things don't figure to get any easier against a good Cubs offense with the wind blowing out at Wrigley Field on Tuesday. Like Beede, Cubs starter Cole Hamels has also struggled lately, giving up 12 earned runs on 17 hits over his last two starts, spanning just five innings. Keep in mind, those two outings came in hitter's parks in Cincinnati and Philadelphia but with excellent hitting conditions expected tonight, again things won't get any easier. Take the over (10*).

My selection is on the 'over' between Chicago and Minnesota at 8:10 pm et on Tuesday.

I expect to see plenty of runs on the board as the White Sox take on the Twins at Target Field on Tuesday night. Reynaldo Lopez will take the ball for Chicago. Sporting a 5.29 ERA and 1.50 WHIP, needless to say he's not enjoying a good season. Lopez has been lit up for 28 hits and 10 earned runs over his last four starts, covering a span of 22 1/3 innings of work. Now he faces a Twins lineup that ranks tied for second in baseball in runs scored and all alone in second in hits. Michael Pineda will counter for Minnesota. The last time he faced the White Sox he gave up just two earned runs in seven innings but now they'll be getting their second look at him in less than a month. Note that the White Sox have now scored a whopping 40 runs in their last six games, including a 6-4 victory here last night. Take the over (10*).

MLB Total of the Week. My selection is on the 'over' between Milwaukee and St. Louis at 7:45 pm et on Tuesday.

We saw a low-scoring game between these two clubs last night as the Cardinals won by a 3-0 score. I'm anticipating more in the way of offensive fireworks on Tuesday, however. Gio Gonzalez will take the ball for the Brewers. He's obviously on the down side of his career and his numbers reflect that this season. Gonzalez has failed to work beyond the fifth inning in any of his last three starts, allowing seven earned runs in 13 innings over that stretch. He's been tagged for four home runs while issuing seven walks over his last two trips to the hill. Michael Wacha will counter for St. Louis. He has recorded an inflated 5.44 ERA and 1.63 WHIP this season and hasn't worked beyond the fifth inning since way back on June 28th. In Wacha's last two outings he has given up eight earned runs in 8 2/3 innings. Take the over (10*).
