Rain or Shine Elasto Painters
Mercado was originally drafted by the Alaska Aces as the fifth pick in the 2008 PBA draft. However, he was immediately traded to the Rain or Shine Elasto Painters, together with Eddie Laure for Joe Devance and the 2009 and 2010 second round picks of Alaska.
With all the focus on Gabe Norwood, that year's first pick overall, and not much hype he scored a record 29 points in his rookie debut game, the highest since Asi Taulava scored 32 points for Mobiline in his debut. Since then, he slowly became one of the PBA's elite point guards.
PBA Fiesta Conference 2009
If not for a hamstring injury that sidelined him in a couple of games into their semifinal series against the Barangay Ginebra Kings, Rain or Shine would have gone farther in the Fiesta Conference. A member of the All-Rookie Team, Mercado finished second to teammate Gabe Norwood for Rookie of the Year honors. Mercado emerged as the team's top scorer with 13.5 points per game and his 4.5 assists per night did not only lead the team but was also number 6 overall among locals. The only glitch in his rookie season was his 2.9 turnovers per game which ranked seventh overall and led the rookies in that category.
Sophomore Season (Philippine Cup)
He has been the team's cornerstone as he always led the Painters to winning games. Against the Coca-Cola Tigers in a knockout game, he scored 28 points to lead them. But unfortunately they would end up short after losing to the Purefoods Tender Juicy Giants.
PBA Fiesta Conference 2010
He averaged 17.7 points in the eliminations then had a 45 point outburst against the B-Meg Derby Ace Llamados. In another knock out game against the Tigers, he delivered crucial plays, despite fouling out, in a come from behind win. Against the Llamados in Game 3, he almost recorded a triple double with 16 points 15 assists 9 rebounds. But, in Game 5 of the series, they lost to the Llamados.
Before the start of the 2011 PBA Commissioner's Cup, he and Jay-R Reyes were among the eight players involved in the three-way trade between Meralco, Rain or Shine and Air21 in what was easily one of the biggest trades that happened this past season. Mercado, along with Paolo Bugia were shipped to the Bolts. He was still able to perform the same way he did with the Elasto Painters. However, it was not enough for the Bolts to past the eliminations of the latter conference.
GlobalPort Batang Pier
Before the start of the 2013 PBA Commissioner's Cup, he along with Kelly Nabong, Jaypee Belencion and Yousif Aljamal were traded to GlobalPort Batang Pier for Rey Guevarra, Vic Manuel, Josh Vanlandingham and 2015 first round pick.
San Miguel Beermen
Before the start of the 2014 PBA Commissioner's Cup, Mercado was traded to San Miguel in exchange for Alex Cabagnot.  At the start of 2014 PBA Governors' Cup, Mercado changed his jersey number from 0 to 7.
Return to GlobalPort
Before the 2014–15 PBA Philippine Cup trade deadline, just before the playoffs, Mercado was traded back to GlobalPort, together with San Miguel's 2018 and 2019 second round picks, in exchange for Cabagnot. 
Barako Bull Energy
Barangay Ginebra San Miguel
On May 4, 2015 before the start of 2015 PBA Governors' Cup Mercado was traded to Barangay Ginebra in exchange of Joseph Yeo.
