For some silly reason, Major League Baseball doesn't allow the trading of first-round draft picks. It does, however, allow the trade of compensatory picks (technically called competitive balance picks) that come right after the first round. Thus, you may see a big trade this week -- already reports are that the Cubs are talking to the Colorado Rockies about Jeff Samardzija and that one of those compensatory picks will be part of the package. The draft starts Thursday. Here's a look at five interesting matchups on Tuesday.

Red Sox at Indians (+105, 8.5)

How baffling have the Red Sox been? Their win Sunday was a seventh straight following a 10-game skid, tying the 1942 Pittsburgh Pirates and 1989 Detroit Tigers for most consecutive victories following a double-digit losing streak. Should Boston have won Monday it can get back to .500 in this game. Jake Peavy (1-2, 4.50) gets the call for Boston. The Sox had lost his past three starts before he allowed three runs in eight innings against Atlanta last time out. The Tribe start T.J. House (0-1, 4.05). Cleveland has lost his two starts, although he was good last time against the White Sox, allowing a run over 6.1 innings. He has never faced Boston.

Key trends: Boston is 1-5 in Peavy's past six road starts. The "over" has hit in four of those.

Early lean: Sox keep it rolling.

Orioles at Rangers (-115, 9.5)

It's questionable whether the Orioles will have major-league home-run leader Nelson Cruz in the lineup on Tuesday, although he's going to play if at all possible against his former Rangers team. He's day-to-day with a left hand contusion after being hit by a pitch. The O's are lucky it wasn't a break. Cruz hits Rangers starter Joe Saunders, a former Oriole, hard. He's 10-for-31 with two home runs career off him. Saunders (0-1, 4.15) returned from a long DL stint in his last start and blanked the Twins over five innings. The Orioles go with Ubaldo Jimenez (2-6, 4.65). The team has lost his past four starts. Adrian Beltre is a career .353 hitter off him with a homer.

Key trends: The Rangers are 2-8 in their past 10 after an off day and have lost five straight Tuesday games. The over is 7-1 in Baltimore's past eight road games against teams with a winning record.

Early lean: Once June hits, always wise to lean over in Arlington. The ball flies out of there in the summer.

Rays at Marlins (-105, 7.5)

Two key hitters will be out of this game. Miami put catcher Jarrod Saltalamacchia on the seven-day concussion disabled list on Sunday. Tampa Bay put 2013 AL Rookie of the Year Wil Myers on the 15-day disabled list with a sprained right wrist. He has been a huge disappointment this season. I expect the Rays to start trading pieces soon -- maybe before Thursday to add a pick. The Rays start Chris Archer (3-2, 4.00) in this one. He has allowed just two earned runs over his past three starts. Archer has never faced the Marlins. The only current Miami player who faced him was Saltalamacchia. Henderson Alvarez starts for Miami. Alvarez (2-3, 2.97) has been spectacular his past two starts, throwing 12 scoreless innings and giving up just nine hits. Evan Longoria feasts off the guy, going 6-for-10 with three home runs.

Key trends: The Marlins are 4-0 in Alvarez's past four at home. The "under" is 8-3 in Archer's past 11 in Game 2 of a series.

Early lean: No Myers and no DH for Rays. Take Miami.

Diamondbacks at Rockies (-155, 10)

The Rockies have the longest losing streak in the National League at four games, and they clearly need to add pitching. It's a vastly different club at home, and this starts a 10-game hoomestand, all against NL West foes. Jorge De La Rosa (6-3, 3.66) starts this series opener. Colorado has won his past six starts. He also has a 2.49 ERA at Coors Field this year. De La Rosa made his season debut against Arizona, allowing four runs in four innings. Cody Ross is 11-for-32 with two home runs off him. Arizona goes with Chase Anderson (3-0, 4.02). He has never faced Colorado.

Key trends: The Rockies are 1-10 in their past 11 against right-handed starters. The under is 8-0 in Arizona's past eight on the road. Colorado is 10-0 in De La Rosa's past 10 at home against Arizona.

Early lean: De La Rosa is apparently invincible at home against Arizona.

Angels at Astros (+120, 8)

The Houston Astros are really getting interesting, and they might be good in 2016. George Springer is a leading candidate for NL Rookie of the Year, and they are calling up another touted prospect. That would be first baseman Jonathan Singleton, who now will start every day. He had 14 homers and 43 RBIs at Triple-A and already has been locked up for at least the next five years. Singleton was acquired from the Phillies in a Hunter Pence deal back in 2011. Singleton will face the Angels' C.J. Wilson in his big-league debut. Wilson (6-4, 3.05) has had three straight quality starts, two of which his team has won. He debuted this season against Houston, allowing a run over eight innings. Houston starts Collin McHugh (3-3, 2.80). The Astros had lost four straight of his starts until he blanked the Royals on five hits over seven innings last time. He allowed two runs over seven innings on May 21 at the Angels.

Key trends: The Angels are 6-0 in their past six series openers when Wilson starts. The over has hit a whopping 17 times in his past 21 series openers.

Early lean: Take the Halos.
