Mariners catcher Jesus Montero will be sent to Triple-A Tacoma today, reports Ryan Divish of The News Tribune. Catcher Jesus Sucre will be selected to join the big league club, and it appears Montero won't do much catching at Triple-A.

It was a blockbuster challenge trade of two extremely promising and valuable young players. Montero had 18 excellent big league games for the Yankees under his belt when he was sent to the Mariners in January 2012. The principal player coming to New York in the deal was soon-to-be 23-year-old righty Michael Pineda, who had averaged nearly 95 miles per hour on his fastball as a rookie, made the All-Star team, and finished fifth in the Rookie of the Year voting. Young players of this caliber are rarely traded. Things went south quickly for Pineda, as decreased velocity in his second Spring Training start was a harbinger of a shoulder injury that would lead to surgery in May 2012. What's more, Pineda was arrested for a DUI in August of that year. Pineda continues to work his way back from the surgery, with the expectation of making his Yankee debut this year. Whether Pineda's rookie campaign was the high point in his career is anybody's guess.

Montero's first full season in 2012 was disappointing. Known almost entirely for his offensive prowess, he posted a .260/.298/.386 line in 553 plate appearances. Montero caught in 56 games, serving as DH in 78. In a full-time catching role this year, he did even less with the bat. As "a man without a position," as Divish puts it, the bar for Montero to become a regular designated hitter in the Majors is quite high. Oh, and the reported connection to Biogenesis doesn't help.

There were a couple of additional players in the Montero-Pineda swap. The Mariners acquired righty Hector Noesi, who hasn't impressed in 120 1/3 big league innings so far. The Yankees added prospect Jose Campos, rated their fifth-best by Baseball America prior to the season. Campos made only five starts last year in low A ball, missing most of the season due to a bone bruise or a small fracture in his elbow. The injury has Campos on an innings limit in the 85-90 range this year.

One year and four months after the exciting Montero-Pineda swap, the players involved in the trade are a mess across the board, which leads to today's poll: which pair of players do you prefer moving forward?
